Tomioka Racing Lightweight Crank Pulley - 2002-2021 Subaru WRX / STI / 2005-2012 Subaru Legacy GT / 1998-2013 Subaru Forester XT

Tomioka Racing Lightweight Crank Pulley - 2002-2021 Subaru WRX / STI / 2005-2012 Subaru Legacy GT / 1998-2013 Subaru Forester XT

The Tomioka Racing Lightweight Crank Pulley removes approximately 4 lbs from the factory unit, reducing the rotational mass the engine must spin at the crankshaft.

Approximately 4 lbs Off the Factory Crank Pulley

The Tomioka Racing Lightweight Crank Pulley removes approximately 4 lbs from the factory unit, reducing the rotational mass the engine must spin at the crankshaft. The reduction in rotational inertia allows the engine to rev more freely and respond more quickly to throttle inputs. CNC machined from 6061 T6 billet aluminum and designed to work with stock or aftermarket belts.

EJ and EJ25 Compatible

Designed for EJ20 and EJ25 applications across the WRX, STI, Legacy GT, and Forester XT lineup. Direct bolt-on replacement for the factory crank pulley. Note: the factory crank pulley on most EJ applications is also a harmonic damper -- removing it eliminates the damping function. Most performance-use EJ builds accept this trade-off, but it is worth noting for primarily street-driven cars.

Straight From Subispeed

One of the more cost-effective rotational mass reductions available for the EJ engine. The 4 lb reduction at the crankshaft is felt most noticeably in throttle response and engine willingness to rev. Pair with the alternator pulley and water pump pulley for a complete lightweight pulley package.
